Port Hamiltonian Systems: A unified Framework fo Modeling and Simulation of Multi-Domain Energy Systems
Modern energy networks demand robust and scalable models that ensure energy conservation, efficient control, and seamless sector coupling. The port-Hamiltonian framework provides a versatile theoretical foundation for modeling diverse physical domains, incorporating concepts such as energy storage, dissipation, and interconnections through mathematical constructs like state variables, Hamiltonian functions, effort and flow variables, and Dirac structures. This study synthesizes insights from existing literature to present a comprehensive summary of the port-Hamiltonian ap- proach and its application to energy network modeling. A simulation is implemented to model a minimal DC power network, including Distributed Generation Units, transmission lines, and nonlinear loads, treated as interconnected port-Hamiltonian systems. Simulation results are compared against Modelica benchmarks, showing strong alignment in both transient and steady-state behavior. Furthermore, Proportional-Integral controllers are integrated into the system to regulate voltage and current setpoints, illustrating the framework’s adaptability for control design. These findings validate the effectiveness of the port-Hamiltonian approach in creating energy-consistent, modular models for multi-domain energy systems.
